Description of Transmitters
Both the 223- to Sc5-ac acd the 1e50- 03 1500-mc transmitters are packaged in a canistar 3-1/2 inches in diameter Sy 15 ioches long.
mate weight of either canister is 91/2 pacds.
Tie saproxni-
Nickel-cacoic battery pwer
supplies were selected ta prowide approxiaarely 50 misutes of cperatisnu.
The
transmitter power supply is switched om ami off, as required, before launch by
a magnetic holdiag relay cootralled by samally actuated signals.
Signals are
sent to the transmitter canister through an explesively actuated disconnect
plug and cable assembly.
Antennas for both bigh- and low-frequency Cransmitter:
are trailizg dipole whips.
Low-Frequency Transaitrer.
